As part of the 2003 redesign, the Savana's front end gained a new grille, bumper, fascia, hood and fenders. Upscale reflector-type headlights were installed, and the taillamps were revamped.

Light-duty vans have rack-and-pinion steering, which promises greater agility. Front and rear suspensions are modified from those used on GM's full-size pickup trucks. The rear suspensions use a solid axle with multileaf springs and gas shocks. All Savanas have 16-inch wheels.

Passenger vans come in regular and extended lengths. The regular-length model has a 135-inch wheelbase and measures 224.1 inches long overall, while the extended-length van rides on a 155-inch wheelbase and stretches 244.1 inches long overall. Each of these vans is 79.4 inches wide and at least 81.6 inches tall.

Regular-length passenger and Cargo Vans can be fitted with a 60/40-split left-side entry and loading door. The side access panels feature remote releases and are limited to work-oriented models. They permit easier accessibility to tools and parts from either side of the van.
